Formula Design Of Nitrile Rubber/PVC Combination To Produce Oil-Resistant Rubber Sheet

Nitrile rubber has good oil resistance and is an ideal raw material for the production of oil-resistant rubber products. The use of PVC in the production of oil-resistant rubber sheets from nitrile rubber can improve the performance of nitrile oil-resistant rubber sheets and improve the processing technology. How to design the formula of nitrile rubber/PVC combined to produce nitrile rubber sheet, what matters should be paid attention to?

1. Rubber material selection

Nitrile rubber has good oil resistance, good chemical resistance and excellent physical and mechanical properties. The use of nitrile rubber to produce oil-resistant rubber sheets can ensure the oil resistance of rubber sheets and improve the physical and mechanical properties and wear resistance of rubber sheets.

PVC is polyvinyl chloride with stable physical and chemical properties, and has a certain resistance to general chemical corrosion. In nitrile oil-resistant rubber sheets, it can improve the anti-aging performance of the rubber compound, and also improve the hardness and oil resistance of the rubber compound.

Appropriate addition of reclaimed rubber to nitrile rubber/PVC compound can reduce production cost and improve processing technology. After nitrile rubber/PVC are used together, the film will not stick to each other, but the surface of the film will not be smooth, and the rubber will easily come off the roll during mixing. These problems can be improved by mixing reclaimed rubber, but the addition of reclaimed rubber should not be too much, otherwise Will reduce the oil resistance of the compound.

2. Selection of compounding agent for nitrile oil-resistant rubber sheet

Sulfur is used as a vulcanizing agent in nitrile rubber/PVC oil-resistant rubber sheet, combined with accelerator CZ/TMTD, active agent zinc oxide and stearic acid to shorten vulcanization time, improve vulcanization efficiency, and improve the aging resistance and wear resistance of rubber compound Wait. The compound with accelerator CZ/TMTD has good scorch safety, fast vulcanization speed and good vulcanization flatness.

Carbon black and calcium carbonate should be used together for the reinforcing filling system, and semi-reinforcing carbon black can be selected for carbon black, which can reduce heat generation and improve the elasticity, aging resistance and mechanical properties of the rubber compound. , increase the volume of the rubber compound.

Dibutyl phthalate in NBR/PVC compounds improves the flexibility of the compound. Pine tar HY23S6J2Y-LYY can improve the flexibility of rubber, help the dispersion of the compounding agent, and improve the cold resistance of the rubber compound.

The anti-aging agent can be selected as a general-purpose anti-aging agent BLE, which is easy to disperse in the rubber compound and has good protection performance against heat, oxygen, ozone and flexing of the oil-resistant rubber sheet.

In the production of oil-resistant rubber sheets from nitrile rubber/PVC, nitrile reclaimed rubber and tread reclaimed rubber can be selected as reclaimed rubbers. The use of reclaimed rubber can not only improve the problems of the rough surfaces and roll off of the film, but also improve the blending. The fluidity, plasticity and calendering of the rubber compound. When designing the formula, the amount of rubber and compounding agent should be reasonably designed.
